NOVELTY - Preparation of polyester fabric having good dyeing properties comprises dissolving graphene in water, sonicating for 30 minutes to obtain 0.12 mg/mL graphene dispersion solution, adding polyester yarn at ratio of 80 g:300-350 mL, heating to 68 degrees C, sonicating for 1.5 hours, filtering, washing with deionized water, and drying; and dissolving graphene quantum dot in water, stirring for 30 minutes to obtain 0.36 mg/mL graphene quantum dot dispersion, adding above polyester yarn at ratio of 100 g:300-350 mL, sonicating for 40 minutes, adding to vacuum reactor, stirring to 92 degrees C at speed of 2500 revolutions/minute for 1 hour, filtering, washing with deionized water, and drying to constant weight. The polyester yarn contains 3.5-5.5 wt.% sodium maleate-diatomite hybrid nanoparticles. USE - Method for preparation of polyester fabric having good dyeing properties. ADVANTAGE - The polyester fabric has higher color fastness.
